ABSTRACT:
In an enabled resume mode, the drive status, head position and recording data amount of a CD-ROM drive are saved in a system memory when the power supply of a system is turned off. When the power supply is turned on, it is determined based on a data recording capacity whether a currently-set CD-ROM is identical with one set when the power supply is turned off. If it is determined that they are not identical, a resume error occurs only in the CD-ROM drive, and the configurations of systems other than the CD-ROM drive are resumed on the basis of information saved in the system memory, thereby preventing the whole system from being hung up.
